+# Code of Conduct
+
+## Our Pledge
+
+In the interest of fostering an open and welcoming environment, we as contributors and maintainers pledge to making participation in our project and our community a harassment-free experience for everyone, regardless of age, body size, disability, ethnicity, gender identity and expression, level of experience, nationality, personal appearance, race, religion, or sexual identity and orientation.
+
+## Our Standards
+
+Examples of behavior that contributes to creating a positive environment include:
+
+* Using welcoming and inclusive language
+* Being respectful of differing viewpoints and experiences
+* Gracefully accepting constructive criticism
+* Focusing on what is best for the community
+* Showing empathy towards other community members
+
+Examples of unacceptable behavior by participants include:
+
+* The use of sexualized language or imagery and unwelcome sexual attention or advances
+* Trolling, insulting/derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or electronic address, without explicit permission
+* Other conduct which could reasonably be considered inappropriate in a professional setting
+
+## Our Responsibilities
+
+Project maintainers are responsible for clarifying the standards of acceptable behavior and are expected to take appropriate and fair corrective action in response to any instances of unacceptable behavior.
+
+Project maintainers have the right and responsibility to remove, edit, or reject comments, commits, code, wiki edits, issues, and other contributions that are not aligned to this Code of Conduct, or to ban temporarily or permanently any contributor for other behaviors that they deem inappropriate, threatening, offensive, or harmful.
+
+## Scope
+
+This Code of Conduct applies both within project spaces and in public spaces when an individual is representing the project or its community. Examples of representing a project or community include using an official project e-mail address, posting via an official social media account, or acting as an appointed representative at an online or offline event. Representation of a project may be further defined and clarified by project maintainers.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be reported by contacting active members of the project team. All complaints will be reviewed and investigated and will result in a response that is deemed necessary and appropriate to the circumstances. The project team is obligated to maintain confidentiality with regard to the reporter of an incident. Further details of specific enforcement policies may be posted separately.
+
+Project maintainers who do not follow or enforce the Code of Conduct in good faith may face temporary or permanent repercussions as determined by other members of the project's leadership.
+
+## Attribution
+
+This Code of Conduct is adapted from the [Contributor Covenant][homepage], version 1.4, available at [http://contributor-covenant.org/version/1/4][version]

NexusUI
+
Web Audio Interfaces
+
Version 2
+
+
+
+
+
+
+
+
+ NexusUI is a collection of HTML5 interfaces and Javascript helper functions to assist with building web audio instruments in the browser.
+
+
+
+ In addition to interfaces, the toolkit contains some helpers for tuning and timing. It does not provide any sound-making capabilities –– for that, check out Tone.js , WebPD , Gibber.lib , or the Web Audio API .
+
+
+
+ This toolkit is designed to help you rapidly prototype your musical ideas. It is lacking some features which would be useful for production –– for example, these interfaces are not responsive (they do not understand percentage widths and heights). NexusUI is an ongoing open-source
+ project; please get in touch on GitHub if you would like to contribute.
+
+
+
+
+
+
Setup
+
+
+ Download NexusUI.js .
+
+
+ Or access on a CDN if you want a hosted file:
+
+
+
+
+
+
+ Link to NexusUI.js in your HTML file.
+
+
+
+<html>
+ <head>
+ <script src="path/to/NexusUI.js"></script>
+ </head>
+ <body>
+
+ </body>
+</html>
+
+
+
Creating an Interface
+
+
+ You can transform regular HTML elements into NexusUI interfaces (<div> is recommended). By default, the interface component will adopt the height and width of the target element as specified in your CSS or in the element's style. Alternatively, you can specify the interface component's
+ size in JavaScript when you create it (see the API for each interface).
+
+
+
+<html>
+ <head>
+ <script src="path/to/NexusUI.js"></script>
+ </head>
+ <body>
+
+ <div id="dial"></div>
+
+ <script>
+ var dial = new Nexus.Dial('#dial')
+ </script>
+
+ </body>
+</html>
+
+
+
+ You can also transform many elements at once by creating a rack .
+
+
+
+
+
+
Dynamically Adding and Removing Interfaces
+
+
+ You can also dynamically add interfaces to your page at any point using Nexus.Add . This lets you add many interfaces to the same parent element. You can later remove the interface using the interface's .destroy() method.
+
+
+
+<html>
+ <head>
+ <script src="path/to/NexusUI.js"></script>
+ </head>
+ <body>
+
+ <div id="instrument"></div>
+
+ <script>
+ var dial = Nexus.Add.Dial('#instrument',{
+ 'size': [100,100]
+ });
+
+ var slider = Nexus.Add.Slider('#instrument',{
+ 'size': [25,100]
+ });
+
+ // then, to remove them tlater
+ dial.destroy();
+ slider.destroy();
+ </script>
+
+ </body>
+</html>
+
+
+
+
+
+
Listening for Interaction Events
+
+
+ Every NexusUI interface fires an event function when the interface is interacted with or changed programatically through the interface's API. If you use Node.JS, this syntax should look familiar –– every NexusUI interface extends Node.js's built-in EventEmitter.
+
+
+
+var dial = new Nexus.Dial("#dial");
+
+dial.on('change',function(v) {
+ // v holds the new numeric value of the dial
+});
+
+
+
+ Many of the core interfaces also fire events on mouse click and mouse release. The following interfaces accept click and release events: button, dial, number, pan, pan2d, position, slider, textbutton, toggle. We hope to develop this feature for all interfaces in the future.
+
+
+
+ var slider = new Nexus.Slider("#slider");
+
+ slider.on('click',function() {
+ console.log('clicked!');
+ });
+
+ slider.on('release',function() {
+ console.log('released');
+ });
+
+
+
+
+
Interface Options
+
+
+ Each interface has an API through which you can customize its values and interaction modes. Common options include:
+
+
+ Setting a numeric range for the value of the interface
+
+
+ Absolute or relative mouse interaction
+
+
+ Vertical, horizontal, or radial (for dials) interaction & orientation
+
+
+
+
+
+ Example:
+
+
+
See the Pen MT - Interface Options Demo by Ben
+ Taylor (@taylorbf ) on CodePen .
+
+
+
Documentation
+
+
+ Check out the API for more details on interface options, as well as for tutorials on tuning and timing mechanisms.
+
+
+
+
+
+
+
+
Colors
+
+
+
+ You can change an interface's colors using .colorize()
+
+
+
See the Pen Colors by Ben Taylor (@taylorbf ) on CodePen .
+
+
+
+
+ Alternately, you can set
Nexus.colors , which will be inherited by every interface created from that point on. This is useful if you want all of your interface components to share the same color scheme.
+
See example on CodePen.
+
+
+
+
+
+
+
+ A complete list of color properties used in the interfaces are:
+
accent ,
+
fill ,
+
dark ,
+
light ,
+
mediumDark ,
+
mediumLight .
+ Not all interfaces use all of these colors.
+
+
+
+
Creating a Rack
+
+
+
+ You can create many interface components at once using Nexus.Rack() . Here is an example:
+
+
+
See the Pen Creating a Rack by Ben Taylor (@taylorbf ) on CodePen .
+
+
+
+
+
+
+ First, create an element that will be the container of the rack.
+
+ Inside that container, create several elements with
nexus-ui attributes describing what type of interface it should transform into, such as
nexus-ui="dial" .
+
+ Give each interface element an ID which will be used to identify it in JavaScript later.
+
+ In your JavaScript, use
new Nexus.Rack("#containerID") to transform the container element into a rack. When this happens, any elements inside the container with valid
nexus-ui attributes will be transformed into interface elements.
+
+
+
Using a Custom Attribute
+
+
+ Nexus.Rack optionally lets you specify which attribute to look for ('nexus-ui' by default). This is useful for using NexusUI with React, which requires data- attribute prefixes.
+
+
+
+ HTML:
+
+
+
+ <div id="target">
+ <div data-nx="dial"></div>
+ </div>
+
+
+
+
+ JS:
+
+
+
+ var synth = new Nexus.Rack("#target",{
+ attribute: 'data-nx'
+ })
+
+
+
+
+
+
Rack Methods
+
+
.hide()
+
.show()
+
.colorize() (See
changing colors )
+
+
+
+
+
+
+
Linking a Number Box to a Dial or Slider
+
+
+
+ A number box can be linked to the value of a dial or slider using .link()
+
+
+
+
See the Pen Number Box Sync by Ben Taylor (@taylorbf ) on CodePen .
+
+
+
+
Tuning
+
+
+ Nexus.note() and Nexus.tune offer ways to manage pitches and scales.
+
+
+
+// Nexus.note(0) returns the frequency of the 1st note of the scale
+synth.frequency.value = Nexus.note(0);
+
+// Nexus.note(2) returns the frequency of the 3rd note of the scale
+synth.frequency.value = Nexus.note(2);
+
+
+
+ By default the scale is an equal-tempered major scale. An API for changing the scale is below.
+
+
+
+ This approach emphasizes algorithmic composition by using numbers to traverse musical scales.
+
+
+
+
+
+
Turning Scale Degrees to Frequency Values
+
+ Nexus.note() provides a method for turning scale degrees into frequency values which your web audio synth will understand.
+
+
+
+
+// Nexus.note(0) returns the frequency of 1st note of the scale
+synth.frequency.value = Nexus.note(0);
+
+// Nexus.note(1) returns the frequency of 2nd note of the scale
+synth.frequency.value = Nexus.note(1);
+
+// Negative numbers wrap to a lower octave
+// Nexus.note(-1) returns the frequency of the top note of the scale, 1 octave lower
+synth.frequency.value = Nexus.note(-1);
+
+// You can also specify the octave using an optional second parameter
+// Nexus.note(0,2) returns the frequency of the 1st note of the scale, 2 octaves up.
+synth.frequency.value = Nexus.note(0,2);
+
+// Nexus.note(0,-1) returns the frequency of the 1st note of the scale, 1 octave lower
+synth.frequency.value = Nexus.note(0,-1);
+
+
+
+ By using counters or number generators in tandem with Nexus.note() , you can play scales, arpeggios, etc.
+
+
+
+
+ // Play 5 octaves of the major scale
+
+ var counter = new Nexus.Counter( 0, 36 );
+
+ var beat = new Nexus.Interval(200,function() {
+ synth.frequency.value = Nexus.note( counter.next() );
+ })
+
+
+
+
+
+
+
Getting Pitch Ratios or adjusted MIDI values
+
+ If working with an audio sample, you may wish to tune your sample by changing its playback speed.
+
+ You can use Nexus.tune.ratio() to get the frequency ratio of a note to the root of your scale. This ratio can be used to set the playback speed of your sample.
+
+
+
+// This gives you the pitch ratio between the 5th note in scale and the root.
+Nexus.tune.ratio(4) // returns 1.49830693925
+
+// You can use this to set the playback speed of a sampler
+sampler.playbackRate = Nexus.tune.ratio(4)
+
+
+
+
+
+
+
+
Changing the Scale
+
+ By default, the scale is an equal-tempered major scale.
+
+
+ We do not provide any other built-in scales. However, we provide two ways for you to create your own scale.
+
+
+
Describing a Scale
+
+ To define your own scale, you can call
.createScale() with a list of the chromatic scale degrees you want in your scale.
+
+
+// Create a minor scale
+Nexus.tune.createScale(0,2,3,5,7,8,10);
+
+// Now, Nexus.note() will refer to the scale you defined
+Nexus.note(0) // returns the frequency number of the root
+Nexus.note(1) // returns the frequency number of a Major 2nd
+Nexus.note(2) // returns the frequency number of a Minor 3rd
+
+
+
+
Describing a Just Intonation Scale
+
+ You can also define
just intonation scales.
+
+ To do so, call
.createJIScale() with your own list of pitch ratios.
+
+
+// Create a major scale in just intonation
+Nexus.tune.createJIScale( 1/1, 9/8, 5/4, 4/3, 3/2, 8/5, 5/3, 15/8 );
+
+
+// Now, Nexus.note() will refer to the scale you defined
+Nexus.note(0) // returns the frequency number for ratio 1/1
+Nexus.note(1) // returns the frequency number for ratio 9/8
+Nexus.note(2) // returns the frequency number for ratio 5/4
+
+
+
+
+
Changing the root
+
+ By default, the root of the scale is Middle C. Therefore, Nexus.note(0) returns the frequency for Middle C.
+
+
+
+ You can set the root using Nexus.tune.root , which is a frequency value.
+
+
+
+// Set the root to 3 octaves below Middle C.
+Nexus.tune.root = Nexus.note(0,-3);
+
+
+ In this way, you can change your scale root on the fly by setting it to other notes of the scale you are currently using.
+
+
+ The root can also be set using traditional musical values like "C3" or "A1". This is the only place in this toolkit where this type of music notation is used.
+
+
+
+// Set the root to low A.
+Nexus.tune.root = "A1";
+
+
+
+
+ You can also set Nexus.tune.root direction to a frequency value, for example if you are working in Just Intonation.
+
+
+
+// Set the root of your scale to 120hz.
+Nexus.tune.root = 120;
+
+
+
+
+
+
+
+
+
+
Timing
+
+
+ Nexus.Interval creates a repeating pulse using WAAClock .
+
+
+
+// Create a pulse of 100ms. At each pulse, the callback function is executed.
+
+var interval = new Nexus.Interval(100, function() {
+ console.log('beep');
+})
+
+
+
+ This interval uses a web audio context to handle timing, so it is more accurate than a regular setInterval or setTimeout
+
+
+
+
+
+
Autostart
+
+
+ Be default, the interval will automatically start when it is created.
+ However a third parameter can set autostart to false.
+
+
+
+// Create a pulse that does not autostart.
+
+var interval = new Nexus.Interval(100, function() {
+ console.log('beep');
+}, false)
+
+
+
+
+
+
Changing the Interval Period
+
+// Change your interval period to 200ms.
+interval.ms(200)
+
+
+
+
+
All methods
+
+// Create a pulse of 1 second
+var interval = new Nexus.Interval(1000, function() {
+ console.log('beep');
+})
+
+// Stop the pulse
+interval.stop();
+
+// Start the pulse
+interval.start();
+
+// Change the interval time
+interval.ms(200);
+
+// Change the function that is called at each pulse
+interval.event = function() {
+ console.log("bloop");
+}
+
+
+
+
+
Matrix Model
+
+
+ The Matrix Model lets you read, write, and manipulate a two-dimensional array of data (such as the data that is visualized by a sequencer ).
+
+
+ Creating a Matrix Model from scratch...
+
+matrix = new Nexus.Matrix(5,10);
+
+
+
+
+
+
+
+
+
+
+
+
+
+
Accessing a Matrix's Values
+
+
matrix.pattern contains a 2-dimensional JavaScript array.
matrix.pattern[0] contains an array of the first row's values.
matrix.pattern[0][0] contains the value of the first cell in the first row.
+
+
+
+var matrix = new Nexus.Matrix(5,10);
+console.log( matrix.pattern );
+
+
+
+
+
+
+
+
+
+
+
+
+
Toggling cells
+
+
matrix.toggle flips a cell or group of cells to their opposite state
+
+
+
+var matrix = new Nexus.Matrix(5,10);
+matrix.toggle.cell(2,2)
+
+
+
+
+
+
+
+
+
+
+
+
+
+matrix.toggle.row(2)
+
+
+
+
+
+
+
+
+
+
+
+
+
+matrix.toggle.column(2)
+
+
+
+
+
+
+
+
+
+
+
+matrix.toggle.all()
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
Setting cells
+
+
matrix.toggle flips a cell or group of cells to their opposite state
+
+
+
+var matrix = new Nexus.Matrix(5,10);
+matrix.set.cell(0,0,1)
+
+
+
+
+
+
+
+
+
+
+
+
+
+matrix.set.row(0,[0,1,0,1,0,1,0,1,0,1])
+
+
+
+
+
+
+
+
+
+
+
+
+
+matrix.set.column(0,[0,1,1,1,0])
+
+
+
+
+
+
+
+
+
+
+
+matrix.set.all([
+ [0,1,0,1,0,1,0,1,0,1],
+ [0,1,0,1,0,1,0,1,0,1],
+ [0,1,0,1,0,1,0,1,0,1],
+ [0,1,0,1,0,1,0,1,0,1],
+ [0,1,0,1,0,1,0,1,0,1]
+])
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
Rotating
+
+
matrix.rotate moves parts of the matrix to the right or left
+
+
+
+var matrix = new Nexus.Matrix(5,10);
+matrix.toggle.cell(0,0)
+
+
+
+
+
+
+
+
+
+
+
+
+
+matrix.rotate.row(0)
+
+
+
+
+
+
+
+
+
+
+
+
+matrix.rotate.row(0,4)
+
+
+
+
+
+
+
+
+
+
+
+
+
+matrix.rotate.column(5)
+
+
+
+
+
+
+
+
+
+
+
+matrix.rotate.all(2)
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
Populating with Patterns
+
+
matrix.populate can set row or column using a pattern.
+
+
+

Populating with Probability
+
+
matrix.populate can set row or column using a pattern of probability values.

Matrix and the Sequencer Interface
+
+ The sequencer interface uses a matrix model to hold its grid of values. You can use any of the above matrix manipulation methods on your sequencer grid, using the sequencer's
.matrix property.
+
+ var sequencer = new Nexus.Sequencer("#target",5,10);
+ sequencer.matrix.toggle.row(2);
+ sequencer.matrix.set.row(1, [0,1,0,1,0,1,0,1,0,1])
+
+
+
+
+
+
+
Counter Model
+
+
+ A Counter model is an object with a minimal API for counting up or down.
+
+
+counter = new Nexus.Counter(0,10)
+counter.next() // returns 0
+counter.next() // returns 1
+counter.next() // returns 2
+// ...
+counter.next() // returns 9
+counter.next() // returns 10
+counter.next() // returns 0
+
+
+
+
+
Modes
+
+ The counter method takes an optional third argument for the counting mode, which can be
up ,
down ,
drunk (randomly chooses to step up or down), or
random (chooses a random number from within the counting range).
+
+
+counter = new Nexus.Counter(0,10,"down")
+counter.next() // returns 10
+counter.next() // returns 9
+counter.next() // returns 8
+
+
+
Properties
+
+
+counter.min = 10
+counter.max = 100
+counter.mode = "down"
+counter.value = 50 // jumps the counter to this value
+
+
+
+
+
Sequence Model
+
+
+ A Sequence model steps through a series of numeric values defined by you.
+
+
+var sequence = new Nexus.Sequence([1,3,5,7])
+sequence.next() // returns 1
+sequence.next() // returns 3
+sequence.next() // returns 5
+sequence.next() // returns 7
+sequence.next() // returns 1
+sequence.next() // returns 3
+
+
+
+
+
Modes
+
+ The sequence model takes an optional second argument for the sequence mode, which can be
up ,
down ,
drunk (randomly chooses to step up or down), or
random (chooses a random number from within the counting range).
+
+
+var sequence = new Nexus.Sequence([1,3,5,7],"down")
+sequence.next() // returns 7
+sequence.next() // returns 5
+sequence.next() // returns 3
+sequence.next() // returns 1
+sequence.next() // returns 7
+sequence.next() // returns 5
+
+
+
Properties
+
+
+sequence.values = [2,4,5,8] // updates the sequence of values
+sequence.mode = "drunk"
+sequence.value = 2 // this jumps to where the '2' value is in the sequence, which is index 0.
+
+
+
+
+
Drunk Model
+
+
+ A Drunk Model does a "drunk walk" through a given range, meaning it will randomly step up or down by a given increment.
+
+
+// This drunk model has a range of 0 to 100
+// Its starting value is 50
+// Its stepping increment is 10
+var drunk = new Nexus.Drunk(0,100,50,10)
+drunk.next() // returns 40
+drunk.next() // returns 50
+drunk.next() // returns 40
+drunk.next() // returns 30
+drunk.next() // returns 40
+drunk.next() // returns 30
+
+
+
+
+
+
Properties
+
+
+drunk.min = 100
+drunk.max = 1000
+drunk.increment = 100
+drunk.value = 500 // jumps to this value

Web Audio Interfaces
+
+
+
+
+
+
+
+
+
+
+ NexusUI is a collection of HTML5 interfaces and Javascript helper functions to assist with building web audio instruments in the browser.
+
+
+
+ In addition to interfaces, it offers a few helper methods for tuning and timing .
+ It does not provide any sound-making capabilities –– for that, check out the Web Audio API or web audio libraries such as Tone.js , WebPD , or Gibber .
+
+
+
+
+
+
+
+
+
+
+
Example
+
+
+
+
Press to Initialize Mobile Audio

+
+ HTML
+
+
<div id="power"><div>
+<div id="gain"><div>
+
+
+ JS
+
+
// Create interfaces
+var power = new Nexus.Toggle("#power");
+var gain = new Nexus.Slider("#gain");
+
+// Create a sound source
+var volume = new Tone.Volume(-Infinity).toMaster();
+var synth = new Tone.Oscillator(300,"sine").connect(volume);
+
+// Listen for interface events
+power.on('change',function(v) {
+ v ? synth.start() : synth.stop();
+});
+
+gain.on('change',function(v) {

+### Framework Size Comparison
+
+| Framework | Version | Minified Size (gzip) |
+|------------------------------------------------|-----------------|----------------------|
+| @angular/core + Polyfills | 7.0.0 | 314.18kb |
+| Ember | 2.18.2 | 121.84kb |
+| Polymer + Web Components Polyfill Lite | 1.8.0 | 66.3kb |
+| Polymer + webcomponents-loader.js + webcomponents-bundle.js |3.0.0 | 45.70kb |
+| React + Map and Set Polyfills | 16.5.2 | 44.75kb |
+| Web Components Polyfill | 0.7.24 | 33.68kb |
+| Vue | 2.5.17 | 31.65kb |
+| __Riot__ | 3.13.2 | 10.85kb |
+| Inferno | 6.0.0 | 7.65kb |
+| Preact | 8.3.1 | 3.48kb |
+
+The above comparison includes polyfills to support old browsers like IE9 that in Riot.js are supported by default.
+
+### Browsers support
+
+Riot is supported by all modern browsers and it does not require any additional polyfill
+
+- IE 9+
+- Edge
+- Chrome
+- Safari 7+
+- Firefox
+- Safari iOS
+- Android
+
+### Custom tags • Concise syntax • Simple API • Tiny Size
+
+Riot brings custom tags to all modern browsers. Think React + Polymer but with enjoyable syntax and a small learning curve.
+
+#### Tag definition
+
+``` javascript
+
+
+ Seconds Elapsed: { time }
+
+ this.time = opts.start || 0
+
+ tick() {
+ this.update({ time: ++this.time })
+ }
+
+ var timer = setInterval(this.tick, 1000)
+
+ this.on('unmount', function() {
+ clearInterval(timer)
+ })
+
+
+```
+
+[Open this example on Plunker](http://riot.js.org/examples/plunker/?app=timer)
+
+#### Mounting
+
+``` javascript
+riot.mount('timer', { start: 0 })
+```
+
+#### Nesting
+
+Custom tags lets you build complex views with HTML.
+
+``` html
+
+
+```
+
+HTML syntax is the de facto language on the web and it's designed for building user interfaces. The syntax is explicit, nesting is inherent to the language and attributes offer a clean way to provide options for custom tags.
+
+
+### Expressions Bindings
+- Absolutely the smallest possible amount of DOM updates and reflows.
+- One way data flow: updates and unmounts are propagated downwards from parent to children.
+- Expressions are pre-compiled and cached for high performance.
+- Lifecycle events for more control.
+
+
+### Close to standards
+- No proprietary event system.
+- Event normalization.
+- The rendered DOM can be freely manipulated with other tools.
+- No extra HTML root elements or `data-` attributes.
+- Plays well with any frontend framework.
+
+
+### Use your dearest language and tools
+- Create tags with CoffeeScript, Jade, LiveScript, Typescript, ES6 or [any pre-processor](http://riot.js.org/guide/compiler/#pre-processors) you want.
+- Integrate with NPM, CommonJS, AMD, Bower or Component
+- Develop with [Gulp](https://github.com/e-jigsaw/gulp-riot), [Grunt](https://github.com/ariesjia/grunt-riot), [Wintersmith](https://github.com/collingreen/wintersmith-riot), [webpack*](https://github.com/riot/tag-loader), [Rollup*](https://github.com/riot/rollup-plugin-riot), [Browserify*](https://github.com/riot/riotify), [Babel*](https://github.com/riot/babel-preset-es2015-riot) or Bublé
+- Test with [Karma*](https://github.com/riot/karma-riot), Mocha or whatever you like
+
+*Note*: `*` officially maintained
+
+### CDN hosting
+- [jsDelivr](http://www.jsdelivr.com/projects/riot)
+- [cdnjs](https://cdnjs.com/libraries/riot)
+
+
+### Concise syntax
+- Power shortcuts: `class={ enabled: is_enabled, hidden: hasErrors() }`.
+- No extra brain load such as `render`, `state`, or `constructor`.
+- Interpolation: `Add #{ items.length + 1 }` or `class="item { selected: flag }"`
+- Compact ES6 method syntax.

+### How to contribute
+
+If you are reading this it's already a good sign and we are thankful for it! We try our best working as much as we could on riot but your help is always appreciated.
+
+If you want to contribute to riot helping us maintaining the project please check first the list of [our open issues](https://github.com/riot/riot/issues) to understand whether there is a task where you could help.
+
+Riot is mainly developed on UNIX systems so you will be able to run all the commands necessary to build and test the library using our [Makefile](Makefile). If you are on a Microsoft machine it could be harder to set up you development environment properly.
+
+Following the steps below you should be able to properly submit your patch to the project
+
+#### 1) Clone the repo and browse to the riot folder
+
+```shell
+$ git clone git@github.com:riot/riot.git && cd riot
+```
+#### 2) Set up your git branch
+
+```shell
+$ git checkout -b feature/my-awesome-patch
+```
+
+#### 3) Install the npm dependencies
+
+```shell
+$ npm i
+```
+
+#### 4) Build and test riot using the Makefile
+
+```shell
+# To build and test riot
+$ make riot
+
+# To build without testing
+$ make raw
+
+# To build anytime you change a src file
+$ make watch
+
+# To bench riot
+$ make perf
+```
+
+#### 5) Pull request only against the `dev` branch making sure you have read [our pull request template](.github/PULL_REQUEST_TEMPLATE.md)
+
+#### 6) Be patient
+
+
